HAY-CARR ER.

Specification of Letters Patent. Patgnteil E1211. 23, 1915.

Appiieation filed October 22, 1913. Serial No. 796,651.

To aZZ whom it may concern Be it known that I, SAMUEL L. HANSON, a citizen of the United States, residing at Albert Lea, in the-county of Freeborn and State of Minnesota, have invented a new and useful i-lay-Carrier, of which the following is a specification.

This invention has reference to improvements in hay carriers requiring a ball or other arrangement attached to the draftrope to enter-the carrier for the purpose of releasing the same from the stop lock on the track or to be used as a registering head for the same purpose.

The object of the present invention is to provide a construction whereby when the carrier is released the device is locked in the carrier and serves as a connection between the carrier and compression pulleys, so that the rope employed is relieved from the weight.

in accordance with the present invention a ball is provided and is so arranged as to be traversed by the rope, while fast to the ball there is a rope clamp constructed to receive a swivel device and the arrangement is such that the ball will sustain the entire weight relieving the rope thereof. The ball and clamp construction is such that the ball I may be employed as a registering head by having it attached directly to the pulley and, moreover, the ball with the clamp in one piece therewith may be attached to the rope at any distance from the pulleys when it is desired that the carrier be unlocked before the load is hoisted clear up.

'i he invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming a part of this specification, with the further understanding that while the drawings show a practical form. of the invention the latter not confined to any strict conformity with the showing of the drawings, but may be changed and modified so long as such changes and modifications mark no material departure from the salient features of the invention as expressed in the claims.

In the drawings :-Figu1 'e 1 is a vertical section of a hay carrier with the invention applied. Fig. 2 is a detail section on a larger scale than Fig. 1 and taken through the ball, clamp and swivel showing the rope in place. and omitting other parts. Fig. 3 is a central section at right angles to the showing of Fig. 2. Fig. 4 is an elevation of the ball and the portion of the rope clamp integral therewith. Fig. 5 is a perspective view oli the swivel adapted to the structure of Fig. Fig. 6 isa clamp block adapted to the structures of Figs. 4 and 5. Fig. 7 is an elevation with some parts in section showing the adaptability of the combined ball and clamp by attachment directly to the pulley and omitting the swivel part. Fig. 8 a view showing a use of the combined ball and clamp.

In Fig. 1 there isshown a hay carrier 1 through which is reeved'a power rope 2, there being pulleys-3, 4 and provided for the purpose, the pulley 5 constituting the compression pulley.

The hay carrier structure in its general form does not form part of the present in vention, and hence is referred to only incidentally as may be necessary for an understanding of the operation of the present invention.

There is provided a device having at one enda-ball 6 which may be in the general form of a hollow truncated sphere open at the truncated portions for the passage of an appropriate portion of the power rope 2. At one open end of the ball there is formed an axial neck 7 continued as a box 8 of general. elongated rectangular form with one side open as indicated at 9. That end of the box 8 remote from the neck 7 has its interior formed into aIv laterally expanded chamber 10 constituting a continuation of the interior of the box, and this chamber terminates in a passagell alined with the elongated interior of the box, the opening through the neck 7 and the openings at the truncated ends of the ball or sphere 6. The opening 11 is of less diameter than the width of the chamber 10, thereby forming a shoulder 12 about the opening 11 except on that side correspond.

ing to the open side 9 of the box 8, at which point the passage 11 is also open laterally to its full diameter.

The box 8 is provided with a closure block 13 havingone face concave, as indicated at 1 1, this being the inner face, and the one presented toward the rear, inner face of the box 8, while through such rear inner face of the box there is provided a passage 15 near but spaced from the point of connection of the box with the neck 7, and through the block 13 is a similar passage 16 which may be somewhat elongated in the direction of rim! '2 and '3.

the length of the block to facilitate the application of a bolt 17 designed to hold the block 15 to the box 8'1 The end of the block 13 corresponding to the opening 11 is formed with a laterally projecting ledge 18 adapted o enter the open side of the passage 11, and

-i,l is ledge has the edge toward the opening 11 concaved, as indicated at 19, while the ity with the chamber 10 and completing and closing such chamber. on opposite sides of the ledge 18 are wings 21 and lugs 22, the lugs engaging the ledge 12 and the wings 21 bearing against the corresponding edges of the open side of the box at the chamber 10. so that the end of the block 13 having the wings 21 enters the box 8 for but a limited distance determined-by the engagement of the wings with the corresponding portion of the box. The main body of the block 13, however, is of such width as to enter the open side of the box 8 freely yet snugly.

When one end of the rope 2 is passed through the ball 6 and neck 7 into the box 8, it is traversed by the bolt 17 and flattened and spread by the block 13, which then acts as an expanded clamp block wedging the end of ,therope into the box 8, which is of greater diameter than the passage through the neck 7, so that the rope becomes-positively clamped against any liability of escape by any force applied short of one suflicient to break the rope.

Piercing the side walls of the box 8 at a point about coincident with the inner end of the chamber 10 are alineti passages 231or a purpose which will presently appear.

Ada ptedto the end of the box 8 remote from the ball 6 is a swivel structure shown separately in Fig. 5, and in detail in Figs. This swivel structure comprises a yokemember 24 having sides 25 connected at one end by a yoke 26 and at the other end formed into spaced cars 27 and introduced between these cars is an eye member 28 formed with a neck .29 terminating at the end remote from the eye in a laterally expanded head 30, the head being substantially flat. The neck 29 is of a size to pass through the opening 11 when the ledge 18 is introduced thereinto, while the head 30 has a lat eral expansion to then engage in the sl1oulder 12 and corresponding wall of the ledge 18, wherefore the swivel member is so held in the box 8 that it may turn freely. about an axis longitudinal of the box and of the ncck'29. The yoke portion of the swivel member is held to the eye 28 by a pivot pin 31 which is customarily riveted at the ends, wherefore the yoke portion of 25 of the swivelanember i l are pierced by alined openings The swivel member is also provided in line ,with the yoke portion 26 with lugs 33 outstanding from the outer faces of the side portions 25.

The hay carrier structure 1 has the pulley I 5 mounted in a frame 34, see Figs. 1 and i traversed by a rod 35 carrying guide sheaves 36 at opposite ends exterior to the frame 3%, and the supporting frame 37 of the pulley 5 is mounted on the rod 35 to turn about the longitudinal axis thereof, while the frame 34 has spaced parallel wings 38 arranged to engage opposite sides of the box 8 with. passages 39 through these wings in alinement with the passages 23, so that a bolt 40 may traverse the alined passages and thus hold the frame 8% to the box 8, the swivel member v24: being then omitted. The Wings 38 have other passages 41 designed to receive lug 12 on the box 8, see Figs. 7 and 8 so that one bolt 40 will hold the frame 34 firmly to the box 8 without liability of the frame moving about the bolt 40 as an axis.

The frame 84: may be applied to the yoke portion of the swivel member by a bolt 43 traversing the passages 32 and 89 when in alinement as shown in Fig. 1, and in this case the lugs 33 lodge in the passages 41, thus holding the frame 3t from turning on the bolt 43.

"With the arrangement shown in Fig. 1 the ball'G willlock in the'carrier, and this ball with the integral attachment to the box- 8 serves as a connection between the carrier and the compression pulleys, so that the load is positively sustained without strain upon the rope, while being transported into the hay mow. Moreover, the clamp arrangement for holding the rope in the box 8 is so related to the rope that it is not in any manner injured and it will notbreak under any strain no matter how heavy which is insuflicient to rupture the rope at other points. double or triple draft. being shown in 1 as arranged for triple draft, while in Fig. 7 the arrangement is such as is employed for double draft, the power rope not being con nected at all to the ball 6 and box 8, while the pulley frame 34 is connected directly to the box 8 instead of to the swivel member 2 1, the latter being then omitted. The ball 6 under these circumstances serves as a registering head.

. There are occasions when it is desired to attach the ball to the power rope at some intermediate point and then the arrangement shown in Fig. 8 is adopted, the clamp block 13 serving the same purpose'as in the structure shown in Figs. 1, 2 and 3, but the The device is adapted for either ferent times at different points.
